For the 2026 tax year, the annual repayment threshold is $24,128 (about $464 a week). You only start repaying once your income for a pay period passes the equivalent weekly, fortnightly, or monthly slice of that threshold.
A flat 12% of every dollar you earn above the threshold, with no upper cap and no brackets. Unlike income tax, which uses progressive brackets, student loan repayments are a single flat rate applied to the portion of income over $24,128 a year.
Yes, if you're a PAYE employee with a student loan, your employer uses an 'SL' tax code (M SL or ME SL) and deducts the 12% repayment automatically alongside income tax, the ACC Earner's Levy, and KiwiSaver, every pay run.
Yes. It's a separate, additional compulsory deduction on top of income tax, the ACC Earner's Levy, and your chosen KiwiSaver contribution rate. On a $65,000 salary, for example, you'd owe income tax and ACC levy regardless, plus a further 12% of the roughly $40,872 above the threshold.
No, not for New Zealand-based borrowers. NZ student loans are interest-free while you live in New Zealand, which is a major difference from many other countries' student loan systems. Interest only applies to borrowers living overseas for more than 183 days.
Yes. You can make voluntary payments directly to IRD on top of your compulsory PAYE deductions to pay off your loan faster, since it's interest-free while you're NZ-based, most people prioritise other goals first, but it's a valid option if your loan balance is small and you want it cleared.
